From CBSNews.com: Skin cancers linked to indoor tanning are estimated to have cost the U.S. health care system hundreds of millions of dollars in 2015, a new study says.

“Skin cancer is the most common cancer in the U.S. and its incidence is increasing, due in part to the increase in the use of tanning devices,” said study author Hugh Waters. He’s a health economist and associate professor at the University of North Carolina School of Nursing.

“We know these devices have significant health and financial impacts, and with this study we wanted to establish these impacts clearly to support efforts to reduce their use, especially among younger people,” Waters added.
